Description

Technical Field

[0001] This invention relates to the field of detection technology, and in particular to an automatic pollution detection device for dissolved oxygen consumption culture. Background Technology

[0002] Dissolved oxygen consumption refers to the amount of dissolved oxygen consumed by microorganisms or chemical oxidation of organic matter and inorganic reducing substances in water under certain conditions. Typically, this refers to filling a completely sealed dissolved oxygen bottle with a water sample. After cultivation, the dissolved oxygen concentration in the water sample before and after cultivation is measured. The difference in dissolved oxygen concentration before and after cultivation is used to calculate the amount of dissolved oxygen consumed per liter of sample, expressed as BOD5. BOD5 (Biochemical Oxygen Demand in Five Days) refers to the dissolved oxygen consumed by microorganisms during the biochemical decomposition of certain organic matter in water over five days under specified conditions. It is an important indicator for determining organic pollutants in water. If the organic matter content in the sample is high, and the BOD5 concentration is greater than 6 mg / L, the sample needs to be appropriately diluted before measurement. For industrial wastewater containing little or no microorganisms, inoculation should be performed when measuring BOD5 to introduce microorganisms capable of decomposing organic matter in the wastewater. When measuring dissolved oxygen, methods such as iodometric titration and electrochemical probe methods are generally used.

[0003] For rod-shaped probes used in electrochemical probe methods, during dissolved oxygen consumption detection, the sealed enclosure necessitates adjusting the probe's insertion depth in the water sample. Therefore, the connection between the probe and the enclosure often relies on flexible connections, such as a flexible tube wrapped around the probe, requiring manual adjustment. However, this manual insertion not only makes precise positioning difficult but also hinders accurate control of the probe's insertion depth at the same location. This results in the probe not being aligned vertically during each measurement, easily causing lateral displacement and leading to data bias. This data is detrimental to comparison of multiple measurements, reducing accuracy and ultimately failing to accurately reflect the true dissolved oxygen consumption trend, thus impacting the reliability of BOD5 test results. Furthermore, the flexible connection cannot be disassembled, making it difficult to quickly replace the probe. For example, in the existing patent CN219758230U, a dissolved oxygen detection device is disclosed. By setting a protective component to cover the probe, it protects the probe. Combined with a protective coating that resists pollution and inhibits biological adhesion to the surface of the detection component, it provides double protection, thus better protecting the probe and extending the service life of the dissolved oxygen detection device. In addition, it can improve the detection accuracy of the dissolved oxygen detection device and overcome the problem that existing sensors are easily adhered to by various organisms when working in water, resulting in short service life and low detection accuracy. This solution can achieve the effect of protecting the probe, but it still cannot guarantee that the probe is in the same position and is difficult to disassemble.

[0004] Therefore, how to provide an automated dissolved oxygen consumption detection device for pollution detection is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to provide an automatic dissolved oxygen consumption culture detection device for pollution detection. The automatic dissolved oxygen consumption culture detection device of the present invention includes an incubator, a detection tube disposed on the incubator, a lifting assembly disposed on the incubator, a clamping assembly disposed on the lifting assembly, a detection component for detecting dissolved oxygen consumption disposed on the clamping assembly, a pushing assembly disposed on the detection component, a support assembly connected to the detection component disposed on the pushing assembly, and a squeezing assembly adapted to the detection tube disposed on the support assembly. A second support component is provided, and a transmission component is provided between the second support component and the first support component. A sealing component is provided on the second support component. When the pushing component is in the first state, the first and second support components are engaged with the detection tube, and the lifting component moves up and down to drive the detection component to move, so that the detection component can detect water samples at different depths. When the pushing component is in the second state, the first and second support components are separated from the detection tube, and the lifting component moves up and down to drive the detection component to move, so that the detection component can be disassembled.

[0006] Preferably, the lifting assembly includes hydraulic lifting rods symmetrically arranged on the incubator, with two hydraulic lifting rods arranged on both sides of the detection tube, and a mounting block provided at the output end of each hydraulic lifting rod.

[0007] Preferably, the clamping assembly includes a clamping rod disposed on the mounting block, the clamping rod passing through the mounting block, a clamping block disposed on the clamping rod, and a clamping spring sleeved on the outer ring of the clamping rod between the clamping block and the mounting block.

[0008] Preferably, the detection component includes a mounting plate that abuts between the two clamping blocks, a detection housing for mounting the processor is provided on the mounting plate, a detection probe is provided on the detection housing, a detection probe is installed at the end of the detection probe, a mounting ring tube is provided on the outer ring of the detection probe, and an annular rubber ring is provided between the mounting ring tube and the detection probe.

[0009] Preferably, the pushing assembly includes an electric push rod hinged to the mounting ring tube, and the output end of the electric push rod is provided with a pushing block.

[0010] Preferably, the support assembly includes a sliding block slidably disposed on the mounting ring tube, a support rod hinged to the sliding block, an L-shaped rod hinged to the push block on the support rod, and a limiting block adapted to the push block on the support rod.

[0011] Preferably, the extrusion assembly includes an extrusion rod slidably disposed on the support rod, an extrusion block is disposed at the end of the extrusion rod, the extrusion block is adapted to the inner wall of the detection tube, and an extrusion spring sleeved on the outer ring of the extrusion rod is disposed between the extrusion block and the support rod.

[0012] Preferably, the second support assembly includes a second support rod hinged to the mounting ring tube, the second support rod being provided with a support block adapted to the detection tube, the second support rod being hinged with a connecting frame, the mounting ring tube being bearing connected to a shaft connected to the connecting frame, and the second support rod being provided with a support spring connected to the mounting ring tube.

[0013] Preferably, the transmission assembly includes a transmission rack disposed on the sliding block, and a transmission gear that meshes with the transmission rack is fixedly sleeved on the shaft.

[0014] Preferably, the sealing assembly includes a sealing ring disposed on the mounting ring tube, a sealing membrane disposed between the sealing ring and the support block, a connecting ring disposed on the sealing membrane, and an elastic band disposed on the connecting ring.

[0015] The beneficial effects of this invention are as follows:

[0016] In use, the detection component is assembled and then placed on the clamping component. The lifting component is then activated, causing it to move the clamping component and the detection component downwards along the detection tube. This causes the detection component to move the pushing component, support component one, pressing component, support component two, transmission component, and sealing component downwards to a suitable position. The pushing component is then activated, moving the pushing component upwards and causing support component one to move upwards. Support component one then moves the transmission component upwards, and the transmission component causes support component two to rotate, causing support component two to abut against the top of the detection tube, achieving a downward limiting effect. Simultaneously, the sealing component forms a seal against the detection tube. The sealing effect of the measuring tube continues until the support component reaches its highest point. Then, the pushing component is activated, preventing the support component from moving upwards and forcing it to rotate. This causes the support component to move synchronously with the squeezing component, bringing it into the hole in the inner wall of the measuring tube, achieving an upward upper limit effect. When testing water samples at different depths, the height of the measuring component needs to be adjusted. Since the measuring component achieves both upper and lower limit effects, the lifting component is activated, causing it to move up and down, forcing the measuring component to separate and thus moving the measuring unit up and down. This system enables the detection of water samples at different depths. During disassembly, the lifting assembly is activated, forcing the detection unit of the detection component to detach from the detection assembly, thus achieving disassembly. Simultaneously, the pushing assembly is activated in reverse, causing the supporting assembly to move downwards and rotate. Under the action of the transmission assembly, the supporting assembly returns to its original state. After the transmission assembly separates, the pushing assembly continues to move downwards, forcing the supporting assembly to return to its original position, causing the detection assembly to separate from the detection tube. When the detection assembly needs to be replaced, the lifting assembly is activated, causing the entire detection assembly to move upwards. When the test tube is exposed, staff will perform a replacement operation. In summary, the automatic pollution detection dissolved oxygen consumption culture detection device of this application utilizes a lifting component to replace manual operation, achieving automatic detection of water samples by the detection component. It can achieve bidirectional positioning of the detection component, ensuring that the detection component is inserted at different depths in the same position, avoiding displacement of the detection component, facilitating the comparison of data from multiple tests, improving the accuracy of the detection data, accurately reflecting the true dissolved oxygen consumption trend, and affecting the reliability of BOD5 detection results. At the same time, the detachable design enables rapid replacement of the detection component. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic pollution detection device for dissolved oxygen consumption culture includes an incubator 1 for culturing microorganisms to detect dissolved oxygen consumption. The incubator 1 has a detection tube 2, which replaces a flexible connection; that is, this solution combines a rigid connection with detachability. The incubator 1 also has a lifting assembly 3, which replaces manual operation for automatic detection. The lifting assembly 3 has a clamping assembly 4 for clamping a detection assembly 5, facilitating disassembly. The clamping assembly 4 has a detection assembly 5 for detecting dissolved oxygen consumption. The detection assembly 5 is a prior art device for detecting dissolved oxygen consumption. The detection assembly 5 has a pushing assembly 6, which provides the driving force. The pushing assembly 6 has a support assembly 7 connected to the detection assembly 5, which provides the connection. The first component 7 is equipped with a compression component 8 adapted to the detection tube 2, which achieves a first-level limit. The detection component 5 is equipped with a second support component 9, which achieves a second-level limit. A transmission component 10 is provided between the second support component 9 and the first support component 7, which has a transmission function. The second support component 9 is equipped with a sealing component 11, which can achieve a sealing effect on the detection tube 2. When the pushing component 6 is in the first state, the first support component 7 and the second support component 9 are engaged with the detection tube 2. The lifting component 3 moves up and down, driving the detection component 5 to move, so that the detection component 5 can detect water samples at different depths. When the pushing component 6 is in the second state, the first support component 7 and the second support component 9 are separated from the detection tube 2. The lifting component 3 moves up and down, driving the detection component 5 to move, so that the detection component 5 can be disassembled.

[0031] Working principle: In use, the detection component 5 is assembled and placed on the clamping component 4. The lifting component 3 is then activated, causing it to move the clamping component 4 and the detection component 5 downwards along the detection tube 2. This causes the detection component 5 to move the pushing component 6, support component 1 7, pressing component 8, support component 2 9, transmission component 10, and sealing component 11 downwards to the appropriate position. The pushing component 6 is then activated, causing it to move upwards, which in turn moves support component 1 7 upwards. Support component 1 7 then moves the transmission component 10 upwards, causing support component 2 9 to rotate. This causes support component 2 9 to abut against the top of the detection tube 2, achieving a downward limiting effect. As a result, the sealing component 11 simultaneously forms a sealing effect on the detection tube 2. After the support component 7 reaches its highest point, the pushing component 6 is activated. The pushing component 6 prevents the support component 7 from moving upwards, forcing it to rotate. This causes the support component 7 to drive the squeezing component 8 to move synchronously, moving the squeezing component 8 into the hole in the inner wall of the detection tube 2, achieving an upward upper limit effect. At this point, when detecting water samples at different depths, the height of the detection component 5 needs to be adjusted. Since the detection component 5 achieves a limit effect both vertically and horizontally, the lifting component 3 is activated, causing it to move up and down, forcing the detection component 5 to separate. The detection unit moves up and down to detect water samples at different depths. During disassembly, the lifting assembly 3 is activated, forcing the detection unit of the detection assembly 5 to detach from the detection assembly 5, achieving disassembly. Simultaneously, the pushing assembly 6 is activated in the reverse direction, causing the support assembly 7 to move downwards and rotate. Under the action of the transmission assembly 10, the support assembly 9 returns to its original state. When the transmission assembly 10 separates, the pushing assembly 6 continues to move downwards, forcing the support assembly 7 to return to its original position, causing the detection assembly 5 to separate from the detection tube 2. When the detection assembly 5 needs to be replaced, the lifting assembly 3 is activated, moving upwards to replace the detection unit. The entire component 5 moves upward and protrudes from the detection tube 2, allowing the operator to replace it. In summary, this application's automatic pollution detection dissolved oxygen consumption culture detection device utilizes the lifting component 3 to replace manual operation, achieving automatic detection of water samples by the detection component 5. It can achieve bidirectional positioning of the detection component 5, ensuring that the detection component 5 is inserted at different depths in the same position, avoiding displacement of the detection component 5, facilitating the comparison of data from multiple tests, improving the accuracy of the detection data, accurately reflecting the true dissolved oxygen consumption trend, and affecting the reliability of BOD5 detection results. At the same time, the detachable design enables rapid replacement of the detection component 5.

[0032] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides an automatic pollution detection device for dissolved oxygen consumption culture. The lifting assembly 3 includes hydraulic lifting rods 301 symmetrically arranged on the incubator 1. The hydraulic lifting rods 301 are used in the prior art to achieve up and down movement. Two hydraulic lifting rods 301 are arranged on both sides of the detection tube 2. The output end of the hydraulic lifting rods 301 is provided with a mounting block 302, which is U-shaped.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic pollution detection dissolved oxygen consumption culture detection device of the present invention includes a clamping assembly 4 comprising a clamping rod 401 disposed on a mounting block 302. The clamping rod 401 is disposed perpendicular to the mounting block 302 and passes through the mounting block 302. A clamping block 402 is disposed on the clamping rod 401 and is adapted to the mounting block 302. A clamping spring 403 is disposed between the clamping block 402 and the mounting block 302 and is sleeved on the outer ring of the clamping rod 401. The clamping spring 403 achieves a clamping effect and improves stability.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic pollution detection dissolved oxygen consumption culture detection device of the present invention includes a detection component 5 comprising a mounting plate 501 abutting between two clamping blocks 402. A detection housing 502 for mounting a processor is mounted on the mounting plate 501. The detection housing 502 contains a processor and other processing electrical components, connected to a guide and control system. A detection probe 503 is mounted on the detection housing 502, having a certain length for easy detection. A detection probe (existing technology) is mounted at the end of the detection probe 503. An installation ring tube 504 is provided around the outer ring of the detection probe 503. An annular rubber ring 505 is provided between the installation ring tube 504 and the detection probe 503, exhibiting friction to achieve a snap-fit ​​connection between the detection probe 503 and the installation ring tube 504.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides an automatic pollution detection device for dissolved oxygen consumption culture detection. The pushing component 6 includes an electric push rod 601 hinged to the mounting ring tube 504. The electric push rod 601 is a prior art device. The output end of the electric push rod 601 is provided with a pushing block 602, which is designed according to requirements.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic pollution detection dissolved oxygen consumption culture detection device of the present invention includes a support component 7 comprising a sliding block 701 slidably disposed on a mounting ring tube 504, the sliding direction of the sliding block 701 being up and down, a support rod 702 hinged to the sliding block 701, the support rod 702 being angled to the sliding block 701, an L-shaped rod 703 hinged to a push block 602 on the support rod 702, the L-shaped rod 703 being fixedly connected to the support rod 702, and a limiting block 704 adapted to the push block 602 on the support rod 702, the limiting block 704 forming an abutment effect when in contact with the push block 602.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic pollution detection dissolved oxygen consumption culture detection device of the present invention includes a squeezing assembly 8 comprising a squeezing rod 801 slidably disposed on a support rod 702. The squeezing rod 801 is disposed along the length direction of the support rod 702. A squeezing block 802 is disposed at the end of the squeezing rod 801. The squeezing block 802 is adapted to the inner wall of the detection tube 2. When the squeezing block 802 contacts the inner wall of the detection tube 2, the squeezing block 802 is located in the hole, achieving a limiting effect. A squeezing spring 803 is disposed between the squeezing block 802 and the support rod 702 and sleeved on the outer ring of the squeezing rod 801.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic pollution detection dissolved oxygen consumption culture detection device of the present invention includes a second support component 9, which includes a second support rod 901 hinged to a mounting ring tube 504. The second support rod 901 provides support, and a support block 902 adapted to the detection tube 2 is provided on the second support rod 901 to achieve an abutment effect. A connecting frame 903 is hinged to the second support rod 901 to adjust the second support rod 901. A shaft 904 connected to the connecting frame 903 is connected to a bearing on the mounting ring tube 504. A support spring 905 connected to the mounting ring tube 504 is provided on the second support rod 901 to achieve a pulling effect and balance the second support rod 901.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic pollution detection dissolved oxygen consumption culture detection device of the present invention includes a transmission component 10 comprising a transmission rack 1001 disposed on a sliding block 701, the transmission rack 1001 being vertically disposed, and a transmission gear 1002 being fixedly sleeved on a shaft 904 and meshing with the transmission rack 1001. When the transmission rack 1001 meshes with the transmission gear 1002, control of the shaft 904 is achieved.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, an automatic pollution detection dissolved oxygen consumption culture detection device of the present invention includes a sealing assembly 11 comprising a sealing ring 1101 disposed on a mounting ring tube 504, the sealing ring 1101 being sleeved on the outer wall of the mounting ring tube 504, a sealing membrane 1102 disposed between the sealing ring 1101 and the support block 902, the sealing membrane 1102 achieving a sealing function, a connecting ring 1103 disposed on the sealing membrane 1102, the connecting ring 1103 being used to support an elastic band 1104, the elastic band 1104 disposed on the connecting ring 1103, when the elastic band 1104 contacts the outer wall of the mounting ring tube 504, achieving a seal between the sealing membrane 1102 and the mounting ring tube 504.

[0041] Working principle: In use, the detection probe 503 is inserted into the mounting ring tube 504, and the detection probe 503 is locked by the annular rubber ring 505. Then, the detection housing 502 and the mounting plate 501 are moved to the vicinity of the clamping block 402. The clamping rod 401 is pulled, and the clamping rod 401 drives the clamping block 402 to move, which compresses the clamping spring 403 and moves the mounting plate 501 between the two clamping blocks 402, forcing the clamping blocks 402 to clamp the mounting plate 501, thereby realizing the installation of the detection housing 502 and the detection probe 503.

[0042] Start the hydraulic lifting rod 301. The output end of the hydraulic lifting rod 301 drives the mounting block 302 to move downward, causing the mounting block 302 to drive the mounting plate 501, the detection housing 502, and the detection probe 503 to move downward along the detection tube 2. This causes the mounting ring tube 504 to drive the pushing assembly 6, the first support assembly 7, the extrusion assembly 8, the second support assembly 9, the transmission assembly 10, and the sealing assembly 11 to move downward to the appropriate position. Start the electric push rod 601. The output end of the electric push rod 601 drives the pushing block 602 to move upward. The pushing block 602 drives the L-shaped rod 703 to move upward. Because the limiting block 704 abuts against the pushing block 602, the first support rod 702, the L-shaped rod 703, and the pushing block 602 become one unit, forcing the pushing block 602 to drive the L-shaped rod 703 and the first support rod 702 to move upward. The first support rod 702 drives the sliding block 701 to move upward. 01 drives the transmission rack 1001 to move upward, which in turn drives the transmission gear 1002 to rotate clockwise. The rotation of the transmission gear 1002 drives the shaft 904 to rotate, which in turn drives the connecting frame 903 to rotate downward. The connecting frame 903 pulls down the support rod 901, so that the support rod 901 overcomes the tension of the support spring 905, causing the support rod 901 to drive the support block 902 to move downward until it contacts the top of the detection tube 2, thus achieving a downward limiting effect. That is, when the hydraulic lifting rod 301 moves downward, it can achieve a limiting effect on the installation ring tube 504. At the same time, the support block 902 drives the sealing membrane 1102 to seal the opening of the detection tube 2. When the sliding block 701 moves to the limit position, the sealing membrane 1102 just completes the covering. The elastic band 1104 locks the sealing membrane 1102 on the outer wall of the detection tube 2, thus achieving a sealing effect.

[0043] Since the sliding block 701 has moved to the highest point, that is, the sliding block 701 has been limited, the electric push rod 601 is activated again, which forces the push block 602 to drive the L-shaped rod 703 to rotate, so that the support rod 702 rotates upward. The support rod 702 drives the extrusion assembly 8 to rotate upward, and the extrusion block 802 contacts the inner wall of the detection tube 2 until the extrusion block 802 moves into the hole in the inner wall of the detection tube 2, thus achieving the upper limit effect. That is, when the hydraulic lifting rod 301 moves upward, it can achieve the limiting effect on the installation ring tube 504.

[0044] When testing water samples at different depths at the same location, the height of the detection probe 503 needs to be adjusted. Since the mounting ring 504 achieves a limiting effect both up and down, when the hydraulic lifting rod 301 is activated for adjustment, it causes the clamping block 402, mounting plate 501, detection housing 502, and detection probe 503 to move up and down. At this time, the detection probe 503 will overcome the friction of the annular rubber ring 505, allowing the detection probe 503 to move up and down within the mounting ring 504, thereby enabling the probe of the detection probe 503 to detect water samples at different depths.

[0045] When disassembling the detection probe 503 and the detection probe, the hydraulic lifting rod 301 is activated, causing the hydraulic lifting rod 301 to move upward, forcing the detection probe 503 to overcome the friction of the annular rubber ring 505 and separate from the mounting ring tube 504. The mounting plate 501 and the detection housing 502 are released by the clamping rod 401 and the clamping block 402, thereby realizing the disassembly of the detection probe 503 and the probe.

[0046] During overall disassembly, the electric push rod 601 is activated in reverse. The electric push rod 601 moves downward, causing the push block 602 to pull down the support rod 702, resulting in the rotation of the support rod 702. This causes the pressing block 802 to disengage from the mounting ring tube 504. Simultaneously, the sliding block 701 moves downward. Under the action of the transmission rack 1001 and transmission gear 1002, the shaft 904 and connecting frame 903 return to their original positions. The connecting frame 903 then drives the second support rod 901 to return to its original position, which in turn drives the support block 902 to return to its original position. This causes the support block 902 to move the sealing membrane. 1102 separates from and opens the detection tube 2. After the transmission rack 1001 separates from the transmission gear 1002, the electric push rod 601 continues to move downward, forcing the push block 602, L-shaped rod 703 and support rod 702 to return to their original positions, so that the mounting ring tube 504 separates from the detection tube 2. At this time, the hydraulic lifting rod 301 is activated. Under the friction of the annular rubber ring 505, the hydraulic lifting rod 301 moves upward, driving the detection housing 502, detection probe 503 and mounting ring tube 504 to move upward until they are exposed from the detection tube 2. The staff then performs the overall replacement operation.

[0047] This solution utilizes the lifting assembly 3 to replace manual operation, achieving automatic detection of water samples by the detection probe 503. On one hand, it enables bidirectional positioning of the installation ring pipe 504, ensuring that the detection probe 503 is inserted at different depths in the same position, preventing displacement of the detection probe 503, facilitating comparison of data from multiple tests, improving the accuracy of the detection data, and accurately reflecting the true dissolved oxygen consumption trend, thus affecting the reliability of BOD5 detection results.
